To obtain such data is challenging, but sequential measurements of stable isotopes (SI) from metabolically inert tissues like dentine allow for chronological reconstruction of SI data that can provide insights into whale life history, behaviour, and physiology. This study examined dentine samples from narwhal embedded canines to reconstruct individual SI profiles and assess intra-annual variation in 15N and 13C. The individual 15N and 13C profiles of all 31 narwhals exhibited cyclical oscillations. The majority of 15N and 13C oscillations (>50%) occurred within the annual growth layer groups (GLGs), suggesting seasonal variation. The mean magnitude of SI oscillations per individual ranged from 0.4 to 2.5 for 15N and 0.2 to 1.1 for 13C. Such intra-annual SI oscillations may reflect variability in narwhal ecology related to environmental variation (e.g., seasonal changes in baseline SI and diet associated with narwhal migration) and/or changes in narwhal physiology (e.g., seasonal energetics), highlighting the utility of SI profiles for long-term monitoring of narwhals ecological and physiological responses to a changing Arctic.Narwhal embedded canines were collected by Inuit during subsistence hunts near Pond Inlet and provided to Fisheries and Oceans Canada through a voluntary collaborative sampling program with the Pond Inlet Hunters and Trappers Association. These harvested narwhals belonged to the Baffin Bay narwhal population, which is monitored by DFO for stock assessment. This research adds to our understanding of this population in terms of their vulnerability and variability to the changing Arctic conditions.","dateModified":"2025-02-14","spatialCoverage":{"geo":{"@type":"GeoShape","box":"72.35633 -81.1066 65.421509 -70.965424"},"@type":"Place"},"distribution":{"contentURL":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13388","@type":"DataDownload"},"url":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13388","datePublished":"2025-01-24","license":"https://www.polardata.ca/pdcinput/public/termsofuse","temporalCoverage":"1982-Jun-2/2017-Aug-13","name":"Stable isotopes (15N and 13C) in dentine growth layer groups (GLGs) of narwhal embedded teeth","publisher":{"@type":"Organization","url":"polardata.ca"},"@id":"CCIN13388" } }, { "@type":"ListItem", "position":2, "item":{ "identifier":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13179","creator":{"creator":{"@type":"Person","name":"Julien Lalibert"},"@type":"Role"},"keywords":"Natural sciences -> Phytoplankton,Geographic locations -> Arctic,Natural sciences -> Ice algae,Natural sciences -> Atmosphere,Natural sciences -> Albedo","contactPoint":[{"@type":"Person","name":"Julien Lalibert"},{"@type":"PropertyValue","email":"julien.laliberte@hotmail.com"}],"@type":"Dataset","description":"Using satellite observations and models, the dataset support a quantitative evaluation of how the transparency of the atmosphere to visible radiation changed over recent times in the Arctic.

This project addresses critical knowledge gaps in pelagic ecosystems, which facilitate better forecasting of how ongoing climatic changes will affect fisheries productivity. Acoustic-trawl surveys from the CCGS Amundsen were conducted from 2017 - 2024 to establish baseline knowledge on the occurrence and distribution of Arctic and boreal pelagic fish and zooplankton in Northern Labrador and the Canadian Arctic, and to continue the ArcticNet time-series initiated in 2003. This datasets concerns the hull-mounted acoustic data that were collected from the Amundsen.","dateModified":"2024-09-16","spatialCoverage":{"geo":{"@type":"GeoShape","box":"82.0 -140.0 52.0 -54.0"},"@type":"Place"},"distribution":{"contentURL":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13165","@type":"DataDownload"},"url":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13165","datePublished":"2020-03-23","license":"https://www.polardata.ca/pdcinput/public/termsofuse","temporalCoverage":"2017-Jun-24/2024-Oct-30","name":"Active Acoustic data in the Labrador Sea and Canadian Arctic (2017-2024)","publisher":{"@type":"Organization","url":"polardata.ca"},"@id":"CCIN13165" } }, { "@type":"ListItem", "position":15, "item":{ "identifier":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=11635","creator":{"creator":{"@type":"Person","name":"Scott Lamoureux"},"@type":"Role"},"keywords":"Natural sciences -> Hydrology,Natural sciences -> Permafrost,Natural sciences -> Water temperature,Natural sciences -> Sediment fluxes,Geographic locations -> Cape Bounty,Natural sciences -> Water chemistry,Natural sciences -> Erosion","contactPoint":[{"@type":"Person","name":"Scott Lamoureux"},{"@type":"PropertyValue","email":"scott.lamoureux@queensu.ca"}],"@type":"Dataset","description":"Five subcatchments, ranging from undisturbed to highly disturbed by 2007-2008 slope failures (active layer detachments) were gauged to assess impacts of disturbance on sediment yield and chemistry.","dateModified":"2024-07-11","spatialCoverage":{"geo":{"@type":"GeoShape","box":"74.9 -109.5 74.9 -109.5"},"@type":"Place"},"distribution":{"contentURL":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=11635","@type":"DataDownload"},"url":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=11635","datePublished":"2013-01-27","license":"https://www.polardata.ca/pdcinput/public/termsofuse","temporalCoverage":"2007-Jun-15/2019-Aug-9","name":"2007-2019 West River subcatchment hydrometric data, Cape Bounty","publisher":{"@type":"Organization","url":"polardata.ca"},"@id":"CCIN11635" } }, { "@type":"ListItem", "position":16, "item":{ "identifier":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13164","creator":{"creator":{"@type":"Person","name":"Jennifer Provencher"},"@type":"Role"},"keywords":"Natural sciences -> Contaminants,Geographic locations -> Baffin Bay,Natural sciences -> Sea birds,Northern communities -> Qikiqtarjuaq,Natural sciences -> Marine birds","contactPoint":[{"@type":"Person","name":"Jennifer Provencher"},{"@type":"PropertyValue","email":"jennifpro@gmail.com"}],"@type":"Dataset","description":"We studied the concentrations of oil-related contaminants in 4 seabird species in the Baffin Bay - Davis Strait region in response to the regional Strategic Environmental Assessment (SEA), which called for a greater understanding of the effects of natural oil seeps and anthropogenic released oil on ecosystems. We found that all seabird species examined have been exposed to naturally occurring types of oil, with levels of oil-related contaminants in coastal benthic feeding species higher than in the species that fed more offshore. There is a growing understanding of how oil pollution can affect aquatic ecosystems, including physical and chemical effects. One of the biggest challenges with detecting the effects of oil-related contaminants on biota is understanding background levels of contaminants due to natural sources and their effects prior to large scale oil and gas operations. Seabirds are effective indicators of pollution, and can be useful for tracking oil-related contaminants in the marine environment.","dateModified":"2024-07-18","spatialCoverage":{"geo":{"@type":"GeoShape","box":"68.0 -65.0 66.0 -63.0"},"@type":"Place"},"distribution":{"contentURL":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13164","@type":"DataDownload"},"url":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13164","datePublished":"2020-03-22","license":"https://www.polardata.ca/pdcinput/public/termsofuse","temporalCoverage":"2018-May-1/2021-Mar-28","name":"Oil-related contaminants in Arctic seabirds","publisher":{"@type":"Organization","url":"polardata.ca"},"@id":"CCIN13164" } }, { "@type":"ListItem", "position":17, "item":{ "identifier":"https://www.polardata.ca/pdcsearch/PDCSearch.jsp?doi_id=13163","creator":{"creator":{"@type":"Person","name":"Trevor Porter"},"@type":"Role"},"keywords":"Geographic locations -> Canada,Geographic locations -> Arctic,Natural sciences -> Oxygen isotopes,Natural sciences -> Ice wedges,Natural sciences -> Paleoclimate","contactPoint":[{"@type":"Person","name":"Trevor Porter"},{"@type":"PropertyValue","email":"trevor.porter@utoronto.ca"}],"@type":"Dataset","description":"The ice wedge oxygen isotope data were collected to better understand long-term changes in the mean winter climate of the study region.

The lack of winter data limits our ability to understand the sensitivity of the winter season to climate forcings such as insolation and greenhouse gas concentration, which is needed to better predict future climate change in the Arctic.
